The subscription architecture in the new system is significantly different from that in the previous system which makes it difficult to support some of the same features.
Keyword Subscriptions
We have requested the keyword subscription functionality, and expect that it will be added to the community early next year. In the meantime, the only workaround I can think of is to configure your subscription notification to include both the message subject and body and subscribe to a Daily Digest for a board. Then you can manually search the notification message for the keywords you are most interested in. I understand that this is not an ideal solution and assure you that this feature is high on our list of priorities.
Multiple Notification Frequency Options
It is my understanding that because of how the subscription code is written, it would be difficult for them to support the multiple notification frequency options that were supported in the previous system. A possible workaround in this scenario would be to maintain multiple user profiles where one is configured to receive digest emails and the other is the active profile that would be configured to receive instant notifications on threads you have posted to. This is a challenge because the user profile system requires that the email addresses be unique, and it is not ideal for users to maintain multiple profiles. I will request the feature again and ask them to reconsider possible implementation options to determine if this is something they could support.
Thanks for the feedback,
